one of the books on Pound has his college transcripts included (I am thinking that it may be J. P. Sullivan's treatment of Pound and Propertius, but could be wrong, way wrong here).  Pound had something like 18 credits of latin--not much, really.  Enough to work translations, but hardly enough to call his Latin excellent by scholarly standards.  This is probably one of the reasons he was attacked by scholars concerning his Propertius--which includes many screwed up interpretations of the Latin--only some of which can be imagined as the result of poetic license.
